The integral, one of the fundamental concepts of Calculus, has a wide application area. This paper focuses on constructing the disk method formula for the volume obtained by revolving a curve around an axis with the help of a CAS. In this study, a semi-structured interview was carried out. In this interview, we tried to construct the disk method formula. The levels of constructing the disk method formula in this study are: \$\bullet\$ Introducing the concept: evaluating the volume of an Egyptian pyramid. \$\bullet\$ Evaluating the volume of a cone obtained by revolution (using Maple worksheet). \$\bullet\$ Designing their own ring and evaluating its price (using Maple). In this study, the interview has been presented as a dialog between teacher and students. When we look at feedback from students, we see that such a teaching method effects students in a positive way and causes them to gain conceptual understanding directed towards the concepts of approximation and volume. rv:
